Study Notes
- Pathology studies disease
Pathology's Role
- Is the bridging subject between clinical and foundational sciences
Scientific Study of Disease
- Pathology focuses on what is abnormal with the goal of diagnosis
- The progression is from normal to abnormal before treatment
Studying Disease
- Definition: Understanding the nature of disease
- Etiology: Identifying disease causes, including predisposing and exciting factors
- Pathogenesis: Understanding the evolution or mechanism of disease formation
- Morphology: Examining structural changes at the normal and microscopic level
- Fate and Prognosis: Predicting the disease's future
- Complications: Investigating added problems in the disease's course
Pathological Investigations
- Biopsy: Examination of living tissue
- Autopsy: Examination of a dead body
Definition of Disease Classifications
- Congenital and hereditary diseases exist
- Acquired diseases include:
- Inflammation
- Degeneration
- Circulatory disturbance
- Tumors
Etiology
- Determining the causes of a disease
- Lesions are structural changes occurring in tissue due to disease
Predisposing Factors
- Factors help in the development of a disease
- Decreased body defense favors infection
- Increased susceptibility is suggested to be hereditary
Exciting Factors
- Direct causes of a disease
- Defective Fetal Development:
- Congenital issues stem from a normal fertilized ovum affected by microbes, drugs, or X-rays in the uterus
- Hereditary factors are inherited from parents
- Acquired Factors:
- Exogenous factors are environmental, such as microbes
- Endogenous factors are internal, such as endocrine disturbance
Pathogenesis
- Examines the mechanisms by which causative agents results pathological changes in tissues
- Focuses on the process of lesion formation
Morphology
- Pathological examination of lesions involves:
- Structural changes in diseased tissues
- Naked eye description of pathological changes
Gross Examination
- Macroscopic picture for:
- Naked eye description of pathological changes
Microscopic Examination
- Histological picture for:
- Changes in cells or tissues are detected via microscopic examination
- Light microscope is used
- Electron microscope is used
- Fluorescent microscope is used
- Immunohistological techniques are used to detect antibodies against components of human cells
Fate and Prognosis
- Forecasting the course and termination of a disease
Complications
- Additional pathological changes occurring during or after the usual course of a disease
- Affects or modifies disease prognosis
Surgical Pathology: Fixation
- Materials obtained are immediately put in fixative fluid to prevent autolysis
- Common fixative fluid is "10% formalin"
Importance of Fixation
- Preserves morphology
- Prevents decomposition and autolysis
- Minimizes microbial or fungal growth
- Minimizes the loss of molecular components
- Good fixation is important for satisfactory histopathology results
Learning Pathology
- General pathology: Common changes in all tissue types
- Systemic pathology: Specific changes in organs and systems
Surgical Pathology
- Examination involves the gross and microscopic analysis of surgical specimens and biopsies from clinicians
- Practice is mandatory for determining diagnosis, treatment, and follow up
Surgical Pathology: Specimens
- Excision biopsy is a therapeutic surgical resection of the entire lesion
- Incision biopsy is a surgical resection of a part of the lesion for diagnosis
- True-cut biopsy retrieves a core of tissue using large bore needles, often guided radiologically
Surgical Pathology: Intraoperative Consultation
- Rapid microscopic examination of fresh tissue
- Used for decisions during operations
Surgical Pathology: Methods
- Frozen section technique is used for preparing histologic slides
- Imprint cytologic slides is preformed
